Genetic mutation trade-offs lead to parallel evolution
Genetic mutation trade-offs parallel evolution
2017/7/20
Organisms in nature adapt and evolve in complex environments. For example, when subjected to changes in nutrients, antibiotics, and predation, microbes in the wild face the challenge of adapting multi...
Identification and characterization of the yls mutation in rice (Oryza sativa L.) with lower photosynthetic pigment content
chloroplast development map-based cloning SRP54 protein yellow-green leaf mutant
2016/12/8
Normal chloroplast development in rice is essential for photosynthesis and yield potential. To explore the physiological and molecular mechanism of chloroplast development, we isolated the rice mutant...
Surface mutation lets canine parvovirus jump to other species
Surface mutation canine parvovirus jumpother species
2016/4/25
Canine parvovirus, or CPV, emerged as a deadly threat to dogs in the late 1970s, most likely the result of the direct transfer of feline panleukopenia or a similar virus from domesticated cats.CPV has...
Crocodilians, including the Australian saltwater crocodile, mutate at about a quarter of the rate of birds, new research has revealed.The discovery is the result of genome sequencing three crocodilian...
Characterization of {\it midline uncoordinated\/}, a mutation affecting behavior and neuroanatomy in Drosophila
Genetics gene gene elements neurons
2014/12/11
Genetic screens which assay behavior have been successfully used to identify genes required for neural function. This thesis is the analysis of midline uncoordinated (muc), a mutation identified for i...
Cloning and functional characterization of the zebrafish mutation belladonna
Belladonna zebrafish mutations mutagenic screen and identify genes the retina the nerve cross the pupil
2014/12/11
The zebrafish belladonna (bel) mutation was identified in a large-scale mutagenesis screen to identify genes involved in retino-tectal pathfinding in Tubingen, Germany. In bel mutants, after exiting t...
A University of Texas at Arlington team exploring pigeons as a model for vertebrate evolution has uncovered that mutations and interactions among just three genes create a wide range of color variatio...
University of Texas (UT) at Arlington researchers, working in parallel with researchers at the University of Utah, examined three genes that control multiple color phenotypes, or appearances, in pige...
Genotype and Allelic Frequencies of a Newly Identified Mutation Causing Blindness in Jordanian Awassi Sheep Flocks
Awassi Sheep, Day Blindness, CNGA3 Gene, PCR- RFLP
2016/5/9
A total of 423 blood samples were collected (during 2009 and 2010) from all the ram holdings at three major Jordanian governmental Awassi breeding stations (Al-Khanasry, Al-Mushairfa and Al-Fjaje) and...
C-sortable words as green mutation sequences
Coxeter group quiver mutation cluster theory exchange graph
2012/5/9
Let Q be an acyclic quiver and s be a sequence s with elements in the vertex set Q_0. We describe a sequence of simple (backward) tilting in the bounded derived category D(Q), starting from the standa...
If K is a knot or link in R3 and S R3 is a smoothly embedded 2-sphere meeting K transversely in 4-points, then one can form a new knot or link K′ as follows. One cuts R3 along S and then glues the t...
We study ‘silting mutaion’ for self-injective algebras. In particular we focus on ‘tilting
mutation’ and show that iterated irreducible ‘silting mutation’ transitively act on the set of silting objec...
On the Impact of Mutation-Selection Balance on the Runtime of Evolutionary Algorithms
Mutation-Selection Evolutionary Algorithms
2011/1/6
The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this interplay is still not completely understood. This paper presents...

The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this inter-play is still not completely understood.
Mutation classes of skew-symmetrizable 3x3 matrices
Mutation classes skew-symmetrizable 3x3 matrices
2011/2/21
Mutation of skew-symmetrizable matrices is a fundamental oper-ation that first arised in Fomin-Zelevinsky’s theory of cluster algebras; it also appears naturally in many different areas of mathematics...
